My 996tt has a sick audio system the previous owner had installed bye Lux. Just recently, even with pioneer avic off, I am getting annoying alternator whine thru the front driver side speaker in dash. Evey speaker in the car is aftermkt and driven by 2 huge amps in the boot. I am going to pop out speaker and see if wire is pinched, but in case it's not simple does anyone have a shop in Monmouth county?
